Latest Galaxies Stories
New research published in the Astrophysical Journal suggests black holes are growing at larger rates than what had previously been thought possible.
Black holes of any size are mysterious, seemingly breaking through the barriers of the physical laws that guide our Universe.
On today’s Your Universe Today podcast, theoretical physicist Dr. Kelly Holley-Bockelmann is back to discuss facts about black holes and help us separate myth from reality.
In this podcast, Dr. John Millis spoke with Vanderbilt's theoretical physicist Kelly Holley-Bockelmann about how stars die and black holes form.
According to a study using data from NASA's Chandra X-ray Observatory, there may be more ultramassive black holes in the Universe than previously thought.
A new study shows that high-speed jets launched from active black holes share fundamental similarities despite the mass, age or environment of their originating black hole.
NASA's Chandra X-ray Observatory has detected a jet of X-rays from a supermassive black hole 12.4 billion light years from Earth, making it the most distant X-ray jet ever observed.
Astronomers have measured the mass of what may be the most massive black hole observed so far by using the Hobby-Eberly Telescope at The University of Texas at Austin's McDonald Observatory.
Supermassive Black Hole -- A Supermassive black hole is a black hole with a mass in the range of millions or billions solar masses. A supermassive black hole has some interesting properties differing from his low-mass cousins: -- The average density of a supermassive black hole can be very low, and actually can be lower than water's density. This happens because the black hole diameter increases linearly with mass, and consequently density drops much faster. -- Strong tidal...
